Linear Regression Model
Model equation:
Yi = α + β × Xi + εi
Top border of price channel:
Exp(Yi) = Exp(a + b × Xi + 2 × s)
Bottom border of price channel:
Exp(Yi) = Exp(a + b × Xi – 2 × s)
where:
i - observation number
Yi - natural logarithm of APTV price
Xi - time index, 1 day interval
σ - standard deviation of εi
a - estimator of α
b - estimator of β
s - estimator of σ
Exp() - calculates the exponent of e
Primary Trend
Start date: January 23, 2023
End date: April 28, 2025
a = 5.6142
b = -0.0009
s = 0.0731
Annual growth rate:
Exp(365 × b) – 1
= Exp(365 × -0.0009) – 1
= -27.30%
Price channel spread:
Exp(4 × s) – 1
= Exp(4 × 0.0731) – 1
= 33.96%

Top border of price channel:
Exp(Y688)
= Exp(a + b × X688 + 2 × s)
= Exp(a + b × 999 + 2 × s)
= Exp(5.6142 + -0.0009 × 999 + 2 × 0.0731)
= Exp(4.8878)
= $132.66
Bottom border of price channel:
Exp(Y688)
= Exp(a + b × X688 – 2 × s)
= Exp(a + b × 999 – 2 × s)
= Exp(5.6142 + -0.0009 × 999 – 2 × 0.0731)
= Exp(4.5954)
= $99.03

Top border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 + 2 × s)
= Exp(a + b × 1,825 + 2 × s)
= Exp(5.6142 + -0.0009 × 1,825 + 2 × 0.0731)
= Exp(4.1663)
= $64.47
Bottom border of price channel:
Exp(Y1,255)
= Exp(a + b × X1,255 – 2 × s)
= Exp(a + b × 1,825 – 2 × s)
= Exp(5.6142 + -0.0009 × 1,825 – 2 × 0.0731)
= Exp(3.8739)
= $48.13
